Reckless gambler Tim Donovan pursues the gang that has just held up the Black Mountain stage. He retrieves the strongbox, but the robbers escape. Bumbling Sheriff Clay Matthews finds Donovan with the loot and arrests him. He is set free by Judge Harper, who knows that Donovan is actually a U.S. Marshal sent undercover to investigate the gang who has been terrorizing the stage line. Donovan discovers a conspiracy involving a bank president and an officer of the stagecoach company. Tim will need to turn up evidence fast, before the criminals are allowed to escape.
